Retractably Clean Toothbrush, with retractable, disposable bristles and audio/visual reminder system

ABSTRACT

This new toothbrush will have a detachable head of bristles and a storage area for new bristles, so that with just the push of a button, the old, dirty bristles drop off, and a new head of bristles slide out. It will also have a built in reminder that flashes red when it&#39;s time to replace it. An LED light (and/or a speaker with a voice recorded on a small computer chip for the more upscale consumer), along with a simple timer device, will remind people that it is time to replace the old bristles with a new set. The new bristle heads will be kept in a storage area in the handle, and additional heads can be in a separate container, much like the blades of a disposable razor. When the handle and container are empty, a refill of new bristles can be purchased at a price for everyday consumers as well as our more elite buyers. In order to shield the bristles that are in use against contamination from other sources when the toothbrush is not in use, the bristle head can be retracted back into the handle&#39;s storage area.

TECHNICAL FIELD AND APPLICABILITY OF THE INVENTION

This invention relates to the area of dental hygiene. The invention relates particularly to an improved design of toothbrush with retractable, disposable bristles and a method of notifying the user that it is time to replace the bristles.

BACKGROUND OF THE INVENTION

This invention idea for a toothbrush that has new bristles come out when you slide the old ones out and push the bottom button to make a new one release came to me during the flu season, but even more so when our daughter was washing out her toothbrush and dropped it in dirty water. She said she was bathing it to get the germs out so she could use it in the morning, but the water was too dirty, so the toothbrush had to be thrown away. This can become expensive when someone has a cold, the flu or some other illness that contaminates their toothbrush every time they use it.

And, for those people who may have had one too many the night before and may want to get a fresh toothbrush after they have brushed out all those germs the next day—instead of going out and buying another toothbrush, they can push the button on the bottom of the toothbrush; the old bristle head drops off in the trash, and a new set of bristles are available.

DESCRIPTION OF THE INVENTION

So, this new toothbrush will have a detachable head of bristles and a storage area for new bristles, so that with just the push of a button, the old, dirty bristles drop off, and a new head of bristles slide out.

It will also have a built in reminder that flashes red when it's time to replace it. An LED light (and/or a speaker with a voice recorded on a small computer chip), along with a simple timer device, will remind people that it is time to replace the old bristles with a new set.

The new bristle heads will be kept in a storage area in the handle, and additional heads can be in a separate container, much like the blades of a disposable razor. When the handle and container are empty, a refill of new bristles can be purchased, and the handle refilled.

In order to shield the bristles that are in use against contamination from other sources when the toothbrush is not in use, the bristle head can be retracted back into the handle's storage area.
